Title: Improvements in or relating to syphon apparatus
IPC: F04F10/00
Filed: 1936-06-16
Abstract: 476,609. Siphons. KODAK, Ltd., SMITH, K. S., and CASBURN, E. V. June 16, 1936, No. 16786. [Class 69 (i)] A pilot siphon tube 1, 2 having an air pressure chamber 4 for initiating the flow in it is connected with a siphon 5, 6 of substantially larger bore so that when the siphons are inunersed the smaller automatically starts the flow in the larger. In the form shown in Fig. 1, the pilot siphon is arranged within the larger, and the lower part of the limb 1 is surrounded by an air-chamber 4 which is perforated at the bottom and communicates at the top through an aperture 14 with the bore of the limb. When the limb is immersed the liquid rises slowly in the chamber and compresses the air in it, which enters the limb 1 through the aperture 14 and forces liquid over the bend of the pilot siphon, thus starting its action. The flow of liquid in the limb 2 exhausts air through a connection 7 from the limb 6 of the main siphon, the lower end of which is initially placed in a liquid seal (not shown), so starting the action of the main siphon. A bend 8 in the limb 2 below the junction of the connection 7 maintains suction in the latter at starting. Fig. 4 shows a modification in which the pilot siphon is outside the main siphon, and the initial liquid seal for the discharge limb of the latter is formed by a cup 16 filled by the discharge from the pilot siphon. A splash guard 19, open at the bottom, surrounds the lower ends of the siphon tubes and the cup 16.

Title: Reproducing quadrophonic sound
IPC: H04H20/88
Filed: 1974-04-17
Abstract: 1427858 Quadraphonic systems CBS Inc 17 April 1974 [17 April 1973] 16797/74 Heading H4R In a matrix decoding system for a quadraphonic sound reproduction system a logic circuit operates by comparing the phases of the signals supplied to the two front reproducers to provide a first phase difference signal, comparing the phases of the signals supplied to the two rear reproducers to provide a second phase difference signal, and then comparing the first and second phase difference signals to provide a control signal which is used to differentially change the gain of amplifiers feeding the front reproducers relative the gain of amplifiers feeding the rear reproducers. As shown in Fig. 1 matrix coded L T  and R T  signals 254 and 256 are applied to a matrix decoder 28 to provide L<SP>1</SP> f , R<SP>1</SP> f , L<SP>1</SP> b , R<SP>1</SP> b  signals. The matrix decoder signals are applied via respective gain controlled amplifiers, 270, 272, 274, 276, to respective loud-speakers, preferably after mixing a small proportion of the opposite channel signal with each of the signals in the combining circuits 278, 280, 282, 284, to improve channel separation, as described in Specification 1,396,352. Control signals for the gain controlled amplifiers are derived in the logic circuit 286 in which the decoder matrix output signals, after opposite channel signals have been mixed in by combiners 288, 290, 292, 294, are amplified and hard limited to provide substantially rectangular waves having the same zero crossings as the input signals. The two limited front signals from limiters 304 and 306 are added in combiner 312 and the resulting wave full wave rectified to provide a signal whose level depends on the relative phase displacement of the L<SP>11</SP> f  and R<SP>11</SP> f  signals. Similarly the combiner 316 and rectifier 318 provides a signal whose level depends on the relative phase displacement of the L<SP>11</SP> b  and R<SP>11</SP> b  signals. The two phase displacement dependent signals are fed to comparator 336 to provide a difference signal which after amplification and shaping is fed, via a limiter 342, rectifier 348, and time constant circuit 352, to control the gain of the amplifiers feeding the front loud-speakers, and also via an inverter 344, limiter 346, rectifier 350 and time constant circuit 354 to control the gain of amplifiers 274 and 276 feeding the rear loud-speakers. The circuit is such that with a predominant front signal amplifiers 270 and 272 have a gain of 1 and amplifiers 274 and 276 a gain 0, the gain values being set by the limiting levels + E 1  and - E 2  of limiters 342 and 346 respectively; while predominantly rear signals will provide gains of 0 for 270 and 272 and 1 for 274 and 276; while with side signals or signals having no predominant directional effect the gains of all amplifiers will be À7, with the range of signal over which the gain remains at À7 being set by the slicers 356 and 358.

Abstract: 1,186,782. Let-off motions. SULZER BROS. Ltd. 13 April, 1967 [13 April, 1966], No. 17031/67. Heading DIE. In a loom having two or more warp beams and a let-off motion including a differential gear to balance the torque applied to the beams to maintain equal thread tension in both beams, the motion includes a gear train of other than 1:1 ratio so that if, e.g. beams of a different width are being used, the total torque applied to each beam is different and thus the tension in each individual thread on both beams is the same. In Figure 1 a sun and planet gear motion 31, let off by an axially movable worm, has its planet gears 25, 26, 28, 29 arranged to give a ratio of 2:1 so that when beams 3, 4 are let off the casing 21 is caused to rotate, because of the ratio, and twice as much torque is delivered, at the same speed, to beam 4, which is twice the width of beam 3, and thus all threads are tensioned equally. In Figure 3 (not shown) the sun and planet tram has a ratio of 1:1 and a gear tram of ratio 2:1 is interposed in the drive to the beams. In Figure 5 (not shown) equal width beams are let off at different tensions by a sun and planet tram of 1:1 ratio and an interposed tram of other than 1:1 ratio. In Figure 7 (not shown), a beam 84 is let off by a 1:1 ratio sun and planet tram 106 which drives a second 1:1 ratio sun and planet tram 151, by a chain and sprocket of other than 1:1 ratio, so that the tram 151 is able to equalise the torque between two beams 133, 134 and thus the individual thread tension on all three beams is the same. The tram 151 may be of other than 1:1 ratio if the beams 133, 134 are of unequal width.

Abstract: 501,799. Materials for diagnosing tuberculosis. EVERY, C. E. (Lakeland Foundation) June 18, 1937, Nos. 17056/37 and 5230 /39 (the second Provisional Specification being divided out of the first Provisional Specification). [Class 81 (i)] An agent specific to tuberculosis, which on injection produces a reaction indicative of the disease when present, is prepared by extracting a protein which is characteristic of tuberculosis from the solid unaffected tissue or from the blood fibrin of an animal suffering from the disease and making an approximately neutral or mildly acid solution thereof. The extracting agent may be a dilute acid or alkaline solution, e.g. of hydrochloric acid, or sodium hydroxide. The solid tissue used may be fibrous connective tissue, muscular tissue or bone marrow. In obtaining the agent from fibrin, blood is coagulated, the clot washed free from haemoglobin and serum, hardened with acetone and dried.; the dried fibrin is then pulverized and extracted with decinormal sodium hydroxide, centrifuged, and the liquid rendered neutral or slightly acid by the addition of hydrochloric acid and potassium phosphate, the final pH preferably being 6-9 Tricresol and glycerine is added to the preparation as a preservative. The agent is similarly obtained from muscular tissue by removing blood and fat, drying, pulverizing and extracting.. If tuberculosis is present in a subject, a slight area of inflammation and the formation of pseudopods is observed round the point of injection.
